Struct casper_execution_engine::shared::account::ActionThresholds

pub struct ActionThresholds { /* fields omitted */ }

Thresholds that have to be met when executing an action of a certain type.

Implementations

impl ActionThresholds

pub fn new(
    deployment: Weight,
    key_management: Weight
) -> Result<ActionThresholds, SetThresholdFailure>

Creates new ActionThresholds object with provided weights

Requires deployment threshold to be lower than or equal to key management threshold.

pub fn set_deployment_threshold(
    &mut self,
    new_threshold: Weight
) -> Result<(), SetThresholdFailure>

Sets new threshold for ActionType::Deployment. Should return an error if setting new threshold for action_type breaks one of the invariants. Currently, invariant is that ActionType::Deployment threshold shouldn't be higher than any other, which should be checked both when increasing Deployment threshold and decreasing the other.

pub fn set_key_management_threshold(
    &mut self,
    new_threshold: Weight
) -> Result<(), SetThresholdFailure>

Sets new threshold for ActionType::KeyManagement.

pub fn deployment(&self) -> &Weight

pub fn key_management(&self) -> &Weight

pub fn set_threshold(
    &mut self,
    action_type: ActionType,
    new_threshold: Weight
) -> Result<(), SetThresholdFailure>

Unified function that takes an action type, and changes appropriate threshold defined by the ActionType variants.

Trait Implementations

impl Clone for ActionThresholds

fn clone(&self) -> ActionThresholds

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ActionThresholds

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for ActionThresholds

fn default() -> Self

Returns the "default value" for a type.

impl<'de> Deserialize<'de> for ActionThresholds

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error> where
    __D: Deserializer<'de>, 

Deserialize this value from the given Serde deserializer.

impl Eq for ActionThresholds

impl FromBytes for ActionThresholds

fn from_bytes(bytes: &[u8]) -> Result<(Self, &[u8]), Error>

Deserializes the slice into Self.

fn from_vec(bytes: Vec<u8>) -> Result<(Self, Vec<u8>), Error>

Deserializes the Vec<u8> into Self.

impl PartialEq<ActionThresholds> for ActionThresholds

fn eq(&self, other: &ActionThresholds) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &ActionThresholds) -> bool

This method tests for !=.

impl Serialize for ActionThresholds

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error> where
    __S: Serializer, 

Serialize this value into the given Serde serializer.

impl StructuralEq for ActionThresholds

impl StructuralPartialEq for ActionThresholds

impl ToBytes for ActionThresholds

fn to_bytes(&self) -> Result<Vec<u8>, Error>

Serializes &self to a Vec<u8>.

fn serialized_length(&self) -> usize

Returns the length of the Vec<u8> which would be returned from a successful call to to_bytes() or into_bytes(). The data is not actually serialized, so this call is relatively cheap.

fn into_bytes(self) -> Result<Vec<u8>, Error>

Consumes self and serializes to a Vec<u8>.
